SIDENECKED DROPPING BOTTLE.

Application filed January 14, 1924. Serial To. 686,026.

To all 1071mm 2'25 may concern:

Be it known that l, HENRY lVns'r, a citizen of the United States of America, residing in the. city of Oakland, and county of Alameda, and State of California, have invented a new and useful Sidenecked Dropping Bottle, of which the following is a specification.

My invention relates to the improvements oi a dropping bottle doing away with comand the objects of my improvements are, first, to allow an easy passage for air to enter the bottle, second, to aiford a simple adjustment for controlling the size and number of drops of liquid and, third, to allow the bottle to be easily refilled or emptied, by pulling the cork out completely.

. l attain these objects as illustrated accompanying drawings in which Figure l, is a cross section of the bottle with cork partly removed.

Figure 2, is an outside view showing the width ofthe liquid passage in the neck, by dotted lines.

Figure 3, is the same as Figure 1, except that the neck of the bottle is completely closed, by the cork.

Referring to the drawings in detail, 1, is the bottle proper, made of glass or other suitable material, 2, is the liquid, 3, the cork or stopper, 4, the neck of the bottle, 5, a groove in the neck which allows the air to enter the bottle, 6, a groove opposite the air groove, which allows the liquid to escape, 7, indicates drops of liquid.

N reference to Figures 1 and 3, it will be noticed that the bottle 1 is shown ona horizontal position and having a peculiar in the shape. the neck 4 being curved up to one side or top; this is done so as the air will have a free passage into the bottle without being likely to come in contact with the liquid which in the case of an ordinary bottle causes, much bubbling.

Grooves 5 and 6, are cast into the bottle when made and, usually opposite, the approximate width is shown by the dotted lines in Figure 2. It will be noticed that these grooves 5 and 6 do not extend the full length of the neck but a certain portion of left round to make a tight joint the neck is when the cork or stopper is inserted as shown in Figure 3.

I will now explain the operation.

The bottle as shown in Figure 3, is closed, to obtain a few drops, the cork 3 is pulled out slightly as in Figure 1, air enters into groove 5 while the liquid enters into groove 6, at a slow rate, going oil into the form of drops 7, it a larger drop or flow is wanted the cork car; he pulled farther out, usually the cork will be held by friction, but if not the forefinger may be placed over the end of same, or cork may be pulled out entirely, and used as an ordinary bottle.

Having thus described my invention, what I cl aim and desire to secure by Letters Patent is A bottle having its neck curved to one side other than its center, whereby the pres sure of the liquid at the dropping surface is reduced, thereby obtaining a slow rate of dropping, and having a groove or channel in its neck to admit air into the bottle, and also having a similar groove or channel in its neck to permit liquids in the bottle to escape in combination with a cork.
